bogofilter-0.14.5.2 - New Stable Release (David Relson)

Bogofilter is a mail filter that classifies mail as spam or ham (non-spam) by a statistical analysis of the message's header and content (body). The program is able to learn from the user's classifications and corrections.
The statistical technique is known as the Bayesian technique and its use
for spam was described by Paul Graham in his article "A Plan For
Spam". Gary Robinson, in his weblog Rants, suggests some refinements for improved discrimination between spam and ham. Bogofilter's primary
algorithm uses the f(w) parameter and the Fisher inverse chi-square
technique that he describes.
Bogofilter is run by an MDA script to classify an incoming message as spam or ham (using wordlists stored by BerkeleyDB). Bogofilter provides processing for plain text and html, supports multi-part mime message with decoding of base64, quoted-printable, and uuencoded text and ignores attachments, such as images.
Bogofilter is written in C. Supported platforms: Linux, FreeBSD, Solaris, OS X, HP-UX, AIX, ...

=================
BOGOFILTER NEWS
=================
0.14.5.2 2003-08-20
* bogominitrain.pl - removed email 'cruft' and revised format
of verbose output.
0.14.5.1 2003-08-19
* Fixed parameter type error in dbh_print_names() that causes
segfault.
* Fixed parsing error that treated "^From " in encoded text as
a message separator.
* Enhanced verbose output of bogominitrain.pl
* Fixed defect in bogominitrain.pl's norepetition mode.
* Documented '-T' option in man page.
* Revised format for '-T'.
0.14.5 2003-08-15
* Corrected parsing error (in html code) that caused
bogofilter to miss message separators.
* Revised processing of From and empty lines so that parsing
works correctly with both flex-2.5.4 and flex-2.5.31.
* Added '-T' as terse mode (with fixed formatting).
* Updated bogominitrain.pl to version 1.3.
* Revised FAQ.
0.14.4 2003-08-10
* Revised database API so that there are 3 distinct layers
(program, datastore, and database) with a clean interface
between them.
* Correct exitcodes in bogoutil by using EX_ERROR.
* Updated FAQ.
* Fixed token registration bug in 0.14.x versions.
* Fixed seg fault caused by database lock contention.
0.14.3 2003-08-05
* Fixed critical locking bug introduced into bogofilter 0.14.0 with
the combined-wordlist code: when working with separate wordlists,
bogofilter would lock only the first one opened, rather than all.
* Documentation updates.
* %g formatting is now supported by bogofilter's formatting functions.
* Merged trio 1.10 (http://ctrio.sourceforge.net/) to support
compilation on ancient systems (Solaris 2.5) that do not have
[v]snprintf functions.
Trio is Copyright (C) 1998-2000 Bjorn Reese and Daniel Stenberg.
* Various documentation updates, including the FAQ.
* The test suite was adjusted for older grep variants (Solaris 2.5)
that don't cope with long lines.
* Print database version in print_version().
* Postfix integration instructions have been upgraded.
* Debug output for wordlists and databases was enhanced.
0.14.2 2003-08-02
* Replaced use of memcpy() by memmove() in an input routine. The
overlapping copy migh cause data corruption on some systems.
* Fixed "make check" failures for bogoutil introduced with the
"combined wordlist" feature in 0.14.0. There has been a buffer
overflow. All users of bogofilter with combined wordlist prior to
0.14.2 are advised to upgrade.
* Fixed bogus "t.valgrind" test FAILures.
* Fixed uninitialized data in db_get_dbvalue(), for split word lists.
* New file, contrib/vm-bogofilter.el, provides an interface
between the VM mail reader and bogofilter."
* Revised lexer_v3.l for compatibility with flex-2.5.31
* Break up long line in regression test input for Solaris 2.5
compatibility.
0.14.1.1 2003-08-01
* Fixed check for adding spam_subject_tag to Subject: line.
* Correct problem with t.degen regression test.
* Updated French version of FAQ.
0.14.1 2003-07-31
* Implemented named exitcodes, with Unsure having its own value (2)
and changing the value for error from 2 to 3.
* Initial release of token degeneration code.
* Revised lexer pattern to better recognize encoded tokens.
* Updated English version of FAQ.
0.14.0.1 2003-07-23
* Fix problem with encoded text.
* Fix handling of absolute paths.
* Fix defect in base64 decoding that can cause segfaults.
* Bogoutil now complains before exiting when it can't open a
file.
* Updated bogominitrain.pl to work with combined wordlists.
0.14.0 2003-07-22
* Initial release of code allowing bogofilter to use a single,
combined BerkeleyDB database for storing both ham and spam tokens.
The file is named wordlist.db
* Default wordlist mode is single, combined wordlist.
File wordlist.db contains all spam and ham tokens.
* Bogofilter and bogoutil detect whether one or two wordlists are in
BOGOFILTER_DIR and use the appropriate wordlist mode (combined or
separate).
* Added tdb (trivial database) support.
* Decode encoded text in header lines.
* Updated contrib/bogominitrain.pl prints more info and can save
messages used in training.
* Bogofilter's -V output now includes algorithm and database info.
* Miscellaneous documentation updates.
